Air conditioner covers are essential for your unit’s overall safety and protection from weather and other elements. When you use covers for your indoor and especially outdoor unit, you significantly increase your unit’s overall lifespan. 

With time, exposure can damage the outer of your air conditioner, and you will end up paying either for repairs or a new unit. To avoid this unwanted and unnecessary cost, you can use an air conditioner cover to keep it away from harm’s way. 

But there are so many AC covers available on the market: which one should you go for? 

To keep things simpler, we have developed this guide to highlight the best air conditioner covers on the market today.

Buying Guide


The most important feature of a window AC cover is its reliability. You need to go for a cover that comes with bungee cords to secure the cover in place on the unit. It will make sure the cover doesn’t get blown away by the wind. 


Your cover will protect your unit from exposure to different elements, including moisture; it needs to have a waterproof design to handle it well. 

Not touching the ground

Make sure to go with a cover that is not touching the ground, or some critters will nest in your AC’s outer and decrease the overall life of your unit. 


Choose an outdoor window air conditioner cover that comes with some additional after-sale service as well. It needs to come with a warranty that solidifies its overall durability. 


You also need to consider its appearance because you don’t want to end up with a glorified tarp. It would be better to go for a cover that adds to the overall quality of your house. 

What air conditioner cover size should I go for? 

Your cover needs to be at least a few inches shorter than the size of the AC to fit nicely and tightly. This way, no moisture will build up inside the cover. 

Are mesh covers good for an AC?

Mesh window AC covers are one of the best types of air conditioner covers. They ensure high airflow and good protection against leaves, debris, and so much more. 

Should I cover my AC in hot weather? 

Most AC routers can withstand typical weather conditions. It can partially handle sun and rain but not the blistering sun or a heavy downpour. So, you should cover your unit but don’t cover it entirely.
